Chapter 2: Preparation
•Power Requirements: Power requirements vary by switch. Refer to Ta b l e 1 for information
regarding your specific system.
Multiple circuits provide redundancy protection. The switch uses power cables that have an
IEC-320 C19 plug. The accessory kit provides IEC-320 C19 to C20 power cables.
Important! All power input plug-socket combinations must be accessible at all times; they provide the primary
method of disconnecting power from the system.
•Other Requirements: Select a site where liquids or objects cannot fall onto the equipment and
foreign objects are not drawn into the ventilation holes. Verify these guidelines are met:
— Clearance areas to the front and rear panels allow for unrestricted cabling.
— All front and rear panel indicators can be easily read.
— AC power cords can reach from the AC power outlet to the connectors on the front panel.
Important! Disconnecting power to all input sockets is required to completely power off the unit.
2.2 Tools Required for Installation
Each switch provides an accessory kit that contains parts for installing the switch into a four-post rack.
Two-post rack mount parts are available through your sales representative. Accessory kits do not
include screws, nuts, or bolts for attaching the switch to a conventional rack.
In addition to the accessory kit, the following tools are required to install a modular switch:
All Racks
• Mechanical device capable of lifting chassis being installed (Chassis weight listed in Ta b l e 1 ).
Two-Po s t C onventional R a ck
• Screws or rack mounting nuts and bolts.
• Screwdriver.
Four-Post Tool-less Rack
No additional equipment required.
Four-Post Conventional Rack
• Screws or rack mounting nuts and bolts.
• Screwdriver.
2.3 Electrostatic Discharge (ESD) Precautions
Observe these guidelines to avoid ESD damage when installing or servicing the switch.
• Assemble or disassemble equipment only in a static-free work area.
• Use a conductive work surfaces (such as an antistatic mat) to dissipate static charge.
• Wear an ESD wrist strap to dissipate static charge accumulation.
• Minimize handling of assemblies and components.
• Keep replacement parts in their original static-free packaging.
• Remove all plastic, foam, vinyl, paper, and other static-generating materials from the work area.
• Use tools that do not create ESD.
